DETAILED DESCRIPTION OF THE INVENTION

(6) FIGS. 1 to 3 show an embodiment of loading and unloading equipment that is labelled with the reference number 2 as a whole. The loading and unloading equipment 2 may be part of a workpiece processing plant and extend to a number of machining tools 4.

(7) The loading and unloading equipment 2 consists of one carrier 8 that essentially runs parallel to the ground 6. The carrier 8 is set in place above the ground 6 by supporting bodies 10 that extend diagonally to the carrier 8. On the carrier 8 a carriage body 12 is installed on which a motor 14 is set, which moves the carriage body 12 along-side the carrier 8 in a direction of movement 16. A loading and unloading device 18 is set on the carriage body 12. Due to the loading and unloading device 18, it is possible to arrange workpieces, tools or the like in the machine tool 4 or remove them from the machine tool 4.

(8) Moreover, the loading and unloading equipment 2 possesses a control device 20, which at least controls the movement of the motor 14 and/or the loading and unloading device 18.

(9) The loading and unloading equipment 2 further includes an access device 22, which consists of a stair-like walk-on element 24 and a locking tool 26. In operating position, the walk-on element 24 extends from near the ground to at least in the direction of the carrier 8.

(10) FIG. 1 shows the locking tool 26 in a release position, in which the locking tool 26 allows access to the walk-on element 24. Thus, it is possible for an operator to access the walk-on element 24.

(11) FIG. 2 shows the locking tool 26 in a locked position, in which the access to the walk-on body 24 is blocked.

(12) The locking tool 26 and the control device 20 are functionally assigned to a safety device 28. The safety device 28 also includes a first sensor tool 30, with which the locking tool's 26 switch from the locked position to the release position is detectable and that in combined effect with the control device 20 sets the motor 14 and/or the loading and unloading device 18 against movement when detecting the locking tool's 26 switch from the locked position to the release position.

(13) FIGS. 1 to 3 show an embodiment of the loading and unloading equipment 2, in which the access device 22 is detachable from the carrier 8. For this purpose, the carrier 8 consists of a gathering device 32, in which the walk-on element 24 of the access device 22 can be set with a setting tool 34 of the safety device 28. In order to set the access device 22 securely in the gathering device 32, the setting tool 34 consists of a latch element 36 that is locked into the gathering device.

(14) In the embodiment shown in the figures, the safety device 28 also includes a second sensor tool 38, with which the locking of the setting tool 34 in the gathering device 32 is detectable. Moreover, the locking of the setting tool 34 in the gathering device 32 may also be displayed by a display tool 40.

(15) In addition, the embodiment depicted in the figures include a railing 42 of the safety device 28, which, in FIG. 1, is placed in a supporting position, in which an operator that accesses the carrier 8 is supported by the railing 42.

(16) FIG. 2 shows the railing 42 in a resting position, in which the railing (seen diagonally to the direction of movement 16) is placed without overlapping with the loading and unloading device 18. In case of the embodiments shown in the figures, the railing 42 lets itself fold from the resting position into the supporting position.

(17) In addition, the railing 42 consists of a cage-like segment 44, which is positioned at the upper end of the walk-on device 24 and surrounds the gathering device 32 in an arched and/or semicircular way.

(18) FIG. 1 shows the loading and unloading equipment 2, where the locking tool 26 is set in a release position. In this case, the railing 42 is also set in a supporting position.

(19) FIG. 2 shows the loading and unloading equipment 2, where the locking tool 26 is set in a locked position. In this case, the railing 42 is set in a resting position.

(20) FIG. 3 shows a top view of the loading and unloading equipment 2. From FIG. 3 it is apparent that the safety device 28 includes a plate-type stepping tool 46, which, at least in the supporting position of the railing 42, overlays the loading and unloading device 18 parallel to the carrier's 8 surface facing away from the ground. Because of this, an operator is able to safely pass the loading and unloading device 18.

(21) FIG. 3 further shows that the loading and unloading equipment 2 possesses a surface element 48 with increased roughness, which is installed on the access device's 24, the carrier's 8 and the stepping tool's 46 surface that faces away from the ground. Due to this surface element 48, the roughness of the surface is increased, reducing the danger of an operator's slipping when accessing the access device 24, the carrier 8 and the stepping tool 46.

(22) The operating principle of the safety device 28 is explained more detailed with the help of the schematic depiction of a procedure for the operation of the safety device 28 of the loading and unloading equipment 2.

(23) In a first step 101, it is detected (by means of a first sensor tool 30 of the safety device 28) whether a locking tool 26 of an access device 22 is arranged in a way that blocks the access to the walk-on element 24, when in a locked position, or allows for access to the walk-on element 24, when in a released position.

(24) In the following step 102, the motor 14 and/or the loading and unloading device 18 is blocked if the locking tool 26 is set to the release position. This is for example shown in FIG. 1.

(25) If necessary, it is possible to perform a step 100 prior to step 101, in the course of which the stepping tool 24 is placed on the carrier 8 and the stepping tool 24 locked in the gathering device 32 with the help of a setting tool 34.

(26) This step may be required of the stepping tool 24 is detachable from the carrier 8 and must be installed on the carrier 8 before accessing the carrier 8.

(27) You may perform steps 101 to 101 prior to step 102. In case of an interim step 101, the second sensor tool 38 first detects, whether the setting tool 34 is locked into the gathering device 32. Only when it is detected that the setting tool 34 is locked into the gathering device 32, is the locking tool 26 of the walk-on element 24 enabled to switch from the locked position to the release position.

(28) This can be followed up by a step 101, i.a. by showing on a display tool 40 that the setting tool 34 is locked into the gathering tool 32.

(29) Lastly, you may perform a procedural step 103, in the course of which the railing 42 is switched from the resting position (FIG. 2) to the supporting (FIG. 1).

(30) The features of the invention disclosed in the foregoing description, in the claims and in the diagrams, may be essential both individually and in any combination in the implementation of the invention in its various embodiments.
